Escape Dead Island is set to launch in North America on November 18 and in the rest of the world on November 21, Deep Silver has confirmed.
Anyone who opts to pre-order and purchase the survival mystery designed to bridge the gap between the original Dead Island and its sequel will apparently be guaranteed access to the Dead Island 2 beta. At the moment it's unclear if this bonus is only available in Europe, but we're working to clarify.
